These are some of the hottest tickets in London, and yet, empty seats have been seen for dozens of events thus far at Olympic venues.

The scene is coming under increased scrutiny in the British media and among locals, particularly on Twitter, and a formal investigation has been launched by the London Organizing Committee for the Olympic Games (Locog).

A Locog spokesman told the BBC: "Where there are empty seats, we will look at who should have been sitting in the seats, and why they did not attend," adding that early indications are that empty seats are in accredited seating areas for press and media.

How did that happen? Blame a mix of prime tickets that go unused by corporate sponsors, international sports federations and rights holders. Adding to the unfortunate visuals: bored media who stay away in droves for preliminary competitions in some sports. It's a common Olympics phenomenon, especially early in the Games when medals aren't yet on the line.

Orwall adds that even some of the athletes have become frustrated, citing a tweet from Indian tennis player Mahesh Bhupathi: "Been trying for 6 hours now to buy my wife a ticket to watch me play tomorrow. Still no luck, and the grounds here feel empty. ABSURD!!!"

Culture Secretary Jeremy Hunt told The Guardian the empty seat problem is being looked at "urgently," noting "if they're not going to turn up, we want those tickets to be available for members of the public, because that creates the best atmosphere."

HuffPost UK readers have been sharing their opinions as well, with one fan calling the empty seats "a disgrace."
